Drilling in the PCB production process


The drilling is all part of the CAD layout whenever there’s a pad there is a hole assigned and allocated in the default setting so you choose the correct size pad with the correct size hole for that component and when we get the plotting done from gerber files we also get a drill plot shows all positions of all the holes with a little grid table showing symbol showing all the different size holes and we could use as a reference for checking the drilling after we’ve drilled it on the CNC drilling machine.
We don’t use it for positioning anything because that is all produced directly from the CAD and gerber files on the CNC drilling machine so there’s no human intervention required so i’ll just show you that on the screen and there you can see all of the pads with all of the holes which is a perfect match obviously for the drill plot.
